Here’s the $8.7bn World’s Biggest Telescope by NASA

The United States National Aeronautics and Space Administration, NASA, said Wednesday it has completed construction of the $8.7 billion James Webb Space Telescope, the largest space telescope ever built, after almost two decades of hard work.

Webb was considered the successor to NASA’s 26-year-old Hubble Space Telescope.

NASA said an Ariane 5 rocket will launch it from French Guiana in October 2018.

“Today, we’re celebrating the fact that our telescope is finished and we’re about to prove that it works,” Nobel laureate and Webb’s senior project scientist John Mather said during a news conference posted on Youtube.

He added that the new telescope will open up “a whole new territory of astronomy.”

“We will see things we have not seen before because this telescope is much more powerful than even the great Hubble telescope,” Mather said.

“To give you some perspective about what we can do with it. If you were a bumblebee at a distance of the moon, we will be able to see you, both by your reflective sunlight and by thermal radiation and heat you emitted.”

According to NASA, its engineers and technicians on Wednesday successfully completed the first important optical measurement of Webb’s fully assembled primary mirror, known as a Center of Curvature test, to measure the mirror’s shape.

NASA said the Webb telescope will be used to observe distant objects in the universe, provide images of the first galaxies formed and see unexplored planets around distant stars.

The $8.7-billion project is led by NASA but also supported by the European Space Agency and the Canadian Space Agency.

According to Wikipedia, NASA science is focused on better understanding the Earth through Earth Observing System, advancing heliophysics through the efforts of the Science Mission Directorate’s Heliophysics Research Program, exploring bodies throughout the Solar System with advanced robotic spacecraft missions such as New Horizons, and researching astrophysics topics, such as the Big Bang, through the Great Observatories and associated programs.

NASA shares data with various national and international organizations such as from the Greenhouse Gases Observing Satellite.
